if part hereof,.Fignre 1 is f it may also niypresent inventionrrel'atesto a coupling fory `said elements whereby .the harvester `will Vbe. securelybut yieldingly connected to permit its vvariable movement, andbyvv'hich be positioned alongsidevthe thrasher to materially reduce the widtliof the machine. for traveling overA roads, through bridges, gates and other passageways.

In thel accompanying.drawing, forming a plan of av combination harvester-thrasher embodying my improvement, Fig. 2 a side elevation of the machine showing furtherdetails of said iinpiovement, andFigQ 3 an "enlarged detail of certain parts. Y

In saiddrawings the portibnsfmarked 5 and 6 indicate the thraslier vand harvester respectively,'supported by: the usual carrying wheels, 7, 8, and provided'with la counterbalancing weight, 9 and othei` details of construction present in` such machines.

In the construction shown I preferably empl-oy an axle, `10, upon which harvester 6 is mounted, to which axle I connect a combined brace and hingefrod, 12, the opposite end of which is provided with a hooker Aeye, 13, linked to a similar device, 14, at-` tached to a frameor brace, 15, of the tlirasher, but where practicable said rod may be connected directly to the thrasher body. The inner end of the axle 10 carries a hook or eye, 16, adapted to be hiiigedly connected to an arm, 18, projecting from the thrasher, or may be connected directly thereto. Said axle is further yieldingly supported by a tension rod, 20,' connected thereto, at 21, and which is maintained in substantially vertical position in a p art of the thrasher, forlexampleas the projecting member, 22, which also acts as a `stop for the spring, 23, coiled about said rod andl which is held in kposition by al nut, 24, or otherwise. By' means ofthe tension rod 2() and the brace and hinge rod 12,1.as will be understood, I Vprovide a flexible connection between the tlirasherand harvester, which may be connected to the axle 10 as shown, or other part ofsaid element, so that the 17,1925., `serial no.y 9,894.

Byl substantially the arrangement 'disclosed it will be understood that the liarf vester is yieldingly connected to the Ythrasher in a manner torperinit its free vibration while traveling, and that certain of the parts may be readily disconnected so that `said harvester may be swung alongside of and in parallel relation to the thrasher.
